摘 要: 提出了一种基于医学图像中感兴趣区域(ROI)的盲检测水印算法, 将包含重要病理信息的灰度图像作为数字水印, 经置乱后在混沌序列的控制下嵌入到宿主小波域非感兴趣区域中。实验结果表明, 该算法在保护医学 ROI 的同时提高了水印抗 JPEG 压缩的鲁棒性, 并对篡改、 几何剪切、 滤波等均具有良好的鲁棒性和透明性, 而且混沌序列增强了系统的安全性。-Abstract: This paper presents a region of interest based on medical ima

在MATLAB水印随基序列生成嵌如到图象中 不错的源码 很好-In MATLAB watermark generated with the base sequence such as embedded to the image of good source is very good
